Dear R users, Can anyone tell me how the medians in survfit() are computed? I´ve looked it up in the source code (print.survfit.s version 4.19 07/09/00), but I´m not a programmer...;-)
Especially, I´d like to know what the pfun() function inside print.survfit.s() works. The help file does describe the calculation of the median, but I´d like to know if and how this differs from just directly calculating the median of the survival times (e.g. using tapply(time,factor,median)). I would be most grateful for any help. Thanks a lot!
